3NB-500A triplex single-acting to-and-fro pump features parameter choice, longer stroke,
larger discharge, reduced stroke number, improved inhaling performance and longer life. It is
specially suitable for oilfield, industry and mine corporation, drilling and well repairing. It is
specially for 15-20 drilling machine.
   The series pump produces strictly according to SY5138 standard production of petroleum
industry department.

3NB-500A single-alone pump unit
 
  Hanging is no need to use a single pump 3NB-500A structureDiesel and deceleration system that is installed in a base, a pump installed in the base alone,Steel shells dowel through the realization of the entire device is connected, easy disassembly and easy transportation is the preferred product oilfield drilling and workover rigs.

  characteristics: Gear from transmission axles, gear box, clutch, with shaft component.Abstract LT600x125 link can be realized through the clutch of pump-driven.Fetal clutch settings provide enough gas to the gap tire removed to facilitate the replacement of airbags, and the friction wheel friction film.The other axis is not necessary to discard parts, a great convenience to users.In the transmission unit is equipped with air compressors, with the level of pressure on the system as a whole, according to the optional pneumatic control system operating pressure.The compressor can be realized automatically opening and closing, the entire pneumatic control system was stable.Fetal gas pedal clutch switches can be deployed in the vicinity of diesel, the Secretary may driller drilling platform in control.Pipeline also has a sea-air valve rapid, in a very short period of time, rapid inflation or exhaust.In addition, customers can request any appropriate to use the engine, clutch and standards converter.Converter can also be installed directly in diesel engines.
